Abstract

Agricultural and forestry waste, as adsorbent materials, offers numerous advantages such as wide availability, low cost, and environmental friendliness, demonstrating broad application prospects. In recent years, the adsorption performance of these materials has been significantly improved through optimization and modification. This review systematically classifies agricultural and forestry waste adsorbent materials, thoroughly summarizes their modification methods, adsorption performance for heavy metals, and factors influencing heavy metal adsorption. It also explores the adsorption mechanisms and the effects of desorption and regeneration, and finally proposes future trends in the research and application of agricultural and forestry waste, providing references for heavy metal pollution control.

Keywords
